Have you been thinking about buying a zero point dry-well? Forget those ugly-looking units the competition makes. Now you can get a great-looking and great-performing zero point dry-well from Hart Scientific.

The Hart Model 9101 has three test wells for inserting more than one probe at a time. All three wells are stable to ±0.01°C. One well accommodates changeable inserts for varying probe diameters.

The Model 9101 takes advantage of the latest solid-state cooling technology rather than relying on older, less reliable sealed-water-cell devices. This eliminates the possibility that the sealed-water cell will freeze and burst while transporting the unit to field locations. And our solid-state cooler is run by an adjustable electronic controller that can be recalibrated in your lab for convenient recertification. Simply place a certified standards thermometer in one of the wells (See Improving Dry-Well Calibrations) and, if needed, tweak the 9101 controller until the standards thermometer reaches equilibrium at 0°C.

Since the unit is completely self-contained and doesn’t require any user settings, you can run it on demand for instant access to an accurate, traceable zero point. Set it up with the reference junction of a thermocouple for high- accuracy thermocouple measurements.

Less costly than refrigerated baths, more accurate and less problematic than ice baths and more durable and better-looking than competitive units using sealed-water cells, the Hart Model 9101 Zero Point Dry-Well is a great choice for any calibration lab.
